Victron VE.Bus BMS NG Battery Management System

The VE.Bus BMS NG is Victron Energy's advanced battery management system for Lithium NG battery banks connected to VE.Bus-compatible inverters and chargers (e.g. MultiPlus, Quattro). It monitors every cell individually, protecting the battery bank against over- and under-voltage, over- and under-temperature, and unintended deep discharge — all things that shorten a lithium battery's lifespan if left unmonitored.

Built-in Bluetooth lets you connect straight to the VictronConnect app for wireless setup, monitoring and firmware updates — no extra cabling to your phone. The BMS talks to other Victron equipment over the VE.Bus network and automatically manages charging and discharging to protect the whole battery bank at once, not just a single cell. It also includes load and charge disconnect outputs, an early pre-alarm for low cell voltage, and LED status/alarm indication for a quick visual check. Note: compatible with Victron's Lithium NG batteries, not the Lithium Battery Smart range.
